4.The concepts described wereappliedto a realisticcase of human inhalation (see Fig.17).Here,the mouth at inhalation was assumed to be an exhaust opening.SVE5 means the portion of the air inhaled.Corresponding to the index IECV,another new index,IECI,showing the effect of contaminant inhalation was defined using the production of the contaminant concentration and SVE5
The more regions there are with low IECI values, the more favorable the environment is for the occupant.
